Three different pesticides were tested in the field to control grape downy mildew in the field of efficacy and efficacy duration. The results showed that 1.0% matrine and sanguinarine 400 times and 40% dimethomorph 500 times were effective in preventing and controlling grape downy mildew in the field, and the holding time was also relatively long The performance of the test agent is more prominent.
